The constant that can be added to
- 3x to form a perfect square trinomial is 
The given expression is
- 3x
To form a perfect square trinomial

The given expression is
- 3x
first we have to add a constant term with it
- 3x + z
By comparing the given expression and the perfect square trinomial

a = x
Similarly
-2ab = 3x
where know a =x
Then,
-2b = 3
b = -3/2
Similarly

= z
9/4 = z
Convert the simple fraction to mixed fraction
9/4 = 
Hence, the constant that can be added to
- 3x to form a perfect square trinomial is

Answer:
15
Since 9 questions is 60% of the exam, you must find 100%. You could find the value of 10% by dividing 60 by 6. You do the same to 9, divide by 6 to get 1.5. Now that you have the value of 10% you can multiply 10% by 10 to get 100. You also do the same to 1.5. Your answer should be 15, if not check your work again.
